Well, my yard is a walk through. And, we get 500+ ToT's, plus parents...
I've found the best means of having the lawn get destroyed by the traffic is to cut it short the week of halloween. (used to be a day before, but I have too much stuff to set up in just a day these days) This also helps eliminate anyone tripping on longer grass.
Our second hear, I had a circle path in the yard, and we had that circle visible most of the following year, due to the trampling.
